Hi- I have a Linux NFS server with two IP addresses: 192.168.1.55: klimt.home 10.0.0.5: klimt-ib.home The server's keytab lists three principals: host/klimt.home@xxxxxxxxxxxxxxxx nfs/klimt.home@xxxxxxxxxxxxxxxx nfs/klimt-ib.home@xxxxxxxxxxxxxxxx When I mount with this: vers=4.0,proto=tcp,sec=sys klimt:/export I get krb5i for lease management, and sys for data traffic. Callback traffic from the server uses krb5i. All well and good. When I mount with this: vers=4.0,proto=tcp,sec=sys klimt-ib:/export I get krb5i for lease management and sys for data traffic as before, and callback traffic attempts to use krb5i. But the client rejects all CB_COMPOUND operations because the callback principal does not match the clp. Looks like the server always uses the nfs/klimt service principal for callback traffic? Is there a way to config the server to use the principal that matches the interface? Or is there something else going on? -- Chuck Lever -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
